The Web component has blocks to convert your JSON text to lists of lists (tables).

That would eliminate all the text replace work.

3

so i need to use json.decode?

4

Sounds good

5

the json decode takes all my list to [1,0]

EDIT: my bad the first json "[" was set to [1, 0] ,[[2,0] it should be [[1,0],[2,0]
